Physical properties
Hardness of 2.5-3 on the Mohs scale, golden-yellow color with a metallic luster, isometric crystal system, and high specific gravity (approx. 19.3).
Formation & geological history
Formed via hydrothermal processes where mineral-rich fluids precipitate gold in quartz veins, later weathered and transported into alluvial placer deposits.
Uses & applications
Widely used in fine jewelry, financial investment, electronics manufacturing, and coveted by mineral collectors.
Geological facts
Gold is extremely malleable and ductile; a single ounce can be drawn into a wire 50 miles long. It does not tarnish or corrode over time.
Field identification & locations
Identified by its high density, softness, and characteristic yellow metallic sheen that does not scratch easily. Commonly found in riverbeds and placer deposits worldwide.
